Beaded Window Casing and Joining methods

Producing the 5/8 bead on a Grizzly G1026 Shaper.   Make sure your featherboards for vertical motion is super-tight, else your bead is ruined.  Depending on the wood, try to get the highest speed as possible to get a good smooth cut.  But of course this depends on the type of wood.  I had to go low speed with my quarter-sawn white oak though.

 Using an MDF male and female mold to create this to make this joint for adjacent windows.  There are other ways.  I think Kreg has a beaded face-frame kit to get this result... but a little bit a scrap MDF will do just fine.  Just use a router to route out the edges using the mold to get consistency everytime.  Same concept as dovetail or box joint jigs work.  Except yours is a double-sided miter on the profiles on male and female sides.

 Not tight enough fit can be fixed with some chisel work.
